General Information and Atomic Structure
Element Name: Antimony
Symbol: Sb
Atomic Number: 51
Atomic Mass: 121.76 amu
Consists of 51 Protons and 51 Electrons
Most Common Isotope: Sb-121
Number of Neutrons in Most Common Isotope: 70 Physical Properties
Solid at Room Temperature
Melting Point: 630.0 °C (903.15 K, 1166.0 °F)
Boiling Point: 1750.0 °C (2023.15 K, 3182.0 °F)
Density @ 293 K: 6.684 g/cm3
Abundance in the earth’s crust: 0.2 to 0.5 parts per million Background
Discoverer: Unknown
Date of Discovery: 3000 BC
Origin of Name: From the Greek words anti (opposed) and monos (solitude), hence "not alone"
Origin of Symbol: From stibium, the ancient name for antimony sulfide
Chemical Family: The Nitrogen Family
Common Uses: hardens lead, plastics, chemicals Chemical Properties
Antimony reacts with Fluorine, Oxygen, Hydrogen and Indium. Antimony Compunds
Antimony pentafluoride (SbF5)
Antimony trioxide (Sb2O3)
Antimony trihydride (SbH3)
Indium antimonide (InSb) Additional
Antimony is used for the hardening of lead to make alloys which are then used in batteries. The hardened alloy also finds use in small arms bullets and tracer rounds and cable sheathing. Although it is too brittle to be of use in its pure form, Antimony makes an excellent alloying material for other metals, providing increased hardness and mechanical strength. Antimony can also be alloyed with Tin to form silverware. Antimony Photo
